This has been a perpetual problem for govt employment. For some jobs we could not even acknowledge product familiarity much less evaluate or offer critical advice. So most of us do what's the next best: use a pseudonym and move on. But employers using online info about a person to make employment decisions is a bad trend. It is just as bad as snooping into my medical records to see if I'm an acceptable risk or weighing the likelihood of maternity leave when hiring women.
